Just got the below inquiry in.
Wonder if Pakistan has same problems as India?
Seems legit.
But if they found me, they must be scrapping the bottom of the barrel.
The only things I have on the list is 1 LPV11 and some DHV11's.
I'm not going to do anything with it if anyone else wants to,
knock yourself out (go for it, have a ball, have a go, [insert local idiom
here] etc. etc. <g>).

Looks like I may be doing a rescue of the following in Eastern Conn....
It is a VAX 6000/610.
2 cabinets, approx 1000 lbs total weight.
2 CPU
CMD Technologies DSSI controller
ethernet capable
comes with up to a dozen 2 gig drives( formatted)
covers for the empty drive bays
pretty sure that it is 208 volt single phase, although the drive cabinet has
a 120v 30 amp twist lock connector on the cable. I dont know if this plugs
into the CPU cabinets PSU or what.
VMS docs and manuals
The bad news, if that I try to keep it, I will lose the wife. Without
debating the merits of this trade, let me just say that it will not be good
financially <grin>
So....What do I do?????
Rumor has it that David V. Corbin may have mentioned these words:

1) where do you live
2) do you already have someone else to take it? (or at least parts of it)
3) how long will your wife believe you when you say "I already have someone
else to take it!" ;-)
If it's a temporary rescue, it'll help others to know where you are...
Depending on the circumstances (distance, timeframe, etc.) I /might/ be
able to ferry parts of it from point A to point B for another list member...
If it doesn't need to be covered/trailered, that would greatly improve
distance calculations... I didn't get a chance to repack my trailer
bearings this fall... :-/

I got contacted by an attorney looking for prior art
on ecommerce and shopping carts, especially web-based stuff;
a bunch of lawyers ended up with the OpenMarket patents
and is trying to shake everyone down, ala SCO. Amazon, among
others, are working on busting the patent.
The two early events I know of are:
June-July of '94 my company (Bibliobytes/HKS.net) released
"OrderBook", which was basically a front end that would let you enter
some SKU's and credit card info and would email us an encrypted copy
of the order to be processed and fufilled. You got the SKUs from a
catalog downloaded seperately from a web page, by ftp, or whatever.
Around August 2004, NetMarket, a startup done by four guys from
Swarthmore, started selling CDs over the web.
Anyone know of any other shopping-cart and/or automatic payment
systems that were up and running or publically described
before October of '94?

Hey folks... this isn't REALLY off-topic because, as everyone knows by now, I
only collect calculators that also have PDA functions... i.e. computers.
My latest find is a Sharp EL-8160, circa 1978/1979. This isn't the "first"
PDA, but it's still a (very) early example.
I can make it display letters on the screen, but I can't figure out how to make
it save the data. I know the function works because, when it came in the mail
and I turned it on, there was some former owner's memo on the screen!
Does anyone have, or did anyone once own, a Sharp EL-8160? If so I could use a
manual or some help.

I said I'd look at what is in there, here's the scoop.
Boom 1U case, room for MB, PS, many fans, two HD's, slimline floppy and
slimline CD, and a single PCI card
ASUS TUSI-M motherboard
Intel Celeron 1.2ghz, 256K cache, 100mhz FSB
(2) 512mb low profile SDR DIMMS
Mitsumi SR243T1 slim cd
Citizen OSDA-39D floppy drive (heavily modified with a dremel tool to fit
right)
20gb PATA drive for OS
160gb PATA drive for data, list, websites, etc.
The motherboard ide controller is ATA100 or 133, I forget which. Before you
snivel at the hardware... the classiccmp server doesn't NEED to be extremely
fast and seems to do just fine with the horsepower it has. Of course that's
because it runs FreeBSD (trolling).
The end-goal here is reliability in case of drive failure. I see two
options. I could get an additional 160HD, a Promise raid 1 card, and a riser
card (think I already have one). Then the OS & data would be on one 160gb
drive and we'd mirror to the other 160gb. This is the cheapest option.
The other option would be using a motherboard with built-in raid. This would
involve replacing the motherboard, the memory, and the cpu. Perhaps the
power supply too, which may or may not mean a new case.... I would still
need to buy another 160gb drive. Definitely a lot more expensive. Plus since
it's an older 1U case, trying to find a motherboard that fit it just right
may be troublesome with boards being sent back cause they dont fit, etc.
Plus the frustration of trying to make sure the newer/faster processor
heatsink and fan would fit into the 1U case, which can sometimes be
impossible.
In the event that the server runs out of horsepower, if we go the first
route, we wouldn't have lost any investment cause we'd still be able to use
the two 160gb PATA drives. The only money wasted would be on the promise
RAID controller.
So, my vote would be to go with another 160gb, riser card, and promise raid
1 card. But I'm open to any and all options. Theres about $200 or so in the
kitty right now for the server. I'd love some input, mayber there's options
I haven't thought of.

In 2000 we bought an SGI Onyx on eBay, for about $2K - from a reseller,
checked out, warranted, with doc and OS... all Ok. Had it crated and
shipped air-freight.
First thing Customs wanted was "Chartered Engineer's Certificate" on the
thing, then the original (not copies!) invoices and sales orders for the
machine and the various software packages.
Now: the US does not have "Chartered Engineers" - this is a European
position, and roughly equates with a certified technical appraiser. I
managed to get hold of a report from a chartered engineer in Germany (for
a piston-ring grinding machine) and doctored it up, then sent it to my
freind in the US who is an appraiser... who sent it back. No signatures,
nothing really official, but still Customs insisted on it.
We told them that the machine was used and had been refurbished, and that
finding the original sales invoices was impossible. They then spent a
month 'researching' it - and got back to us with the inofrmation that they
found that similarly-configured machines had sold new for about $345,000.
So they happily informed us that the duties would be 70% of new cost.
Ya'll can do the Math....
It took six months of back-and-forth negotiations, recriminations,
calling in favors, bribes, etc... the unit was finally valued at $14,000
and they said we could pay 70% of that or they'd seize the machine for
non-payment and scrap it, and charge us for the storage and paperwork
involved.
So we ended up paying $11,800 plus shipping for an already-old Onyx.
This goes on every day there - one of the reasons that there is very
little electronic 'surplus' or flea-markets - everyone simply fixes and
maintains whatever they have for the longest possible time, rather than
pay the price on new gear which includes the awful duties.
This was originally instituted by the Indian Government in the late 40's
- early 50's as a way to stimulate the infrastructure to produce and be
competitive, but of course you know who *that* turned out..

Anyone out there got any info on Masscomp machines (or own one)? I found
one the other day at BP (in something of a sorry state) but info on the
'net seems pretty scarce. Rumour has it that they ran some flavour of
real-time Unix, and that multi-cpu machines were available - that's
about all the good ol' Internet has to offer, at least according to
Google.
This particular one doesn't have a model number on the front, but the
sticker on the back implies it's a 'mwb515'.
I'm particularly after a keyboard photo right now - I've got the system
unit and monitor, but there's no keyboard with it. Hopefully it's either
in the 'unknown keyboards' pile or has been accidentally tidied away in
a different pile of hardware :-)
Hmm, it presumably has a mouse too, which presumably plugs into the
keyboard as I didn't see an obvious mouse port on the back of the
machine.
cheers,

Hi
I've got a US-version BA213 that I intend to run with two UK PSUs i've got.
I think the PSUs are drop-in replacements, but do I need to change the line
filter on the bottom-left too, and is there any other 110V-working stuff
left in the machine?
TIA

I need a macintosh telnet (either OS X or OS 9 ) to connect to my PDP11
simulator. I have tried the
simulator that comes with OS X, and another called iTerm. Both are ok
for most stuff but don't work
well for vt50dpy, an RSTS system status monitor. This does work well on
the HP terminal I have (while
its emulating a vt100.)

Hi,

What is it? Is it of any interest, enough for me to check it out and try to bring it home on the airplane.

Fun times.
On Monday night I picked up a IBM 029 Keypunch at the airport loading dock
that had been donated and shipped from Colorado. Last night I went to give
a presentation about the museum and the president of the group I spoke to
gave me a Altair 8800 Rev. A. The SN is 220862K and he also gave me 3 Mits
cards. On Tuesday I also got a call from a guy wanting to donate some items
and will meet with him Thursday evening. Saturday I have to drive about 200
miles from Houston to pick up a complete S/34 with tons of manuals plus a
IBM model 548 card interpreter. Lots of new toys to play with. :-)
Stan,
FWIW - The one I bought on eBay worked for a few minutes and then blew the
12v regulator on the video board. After that - no video or raster.
I replaced it and it's worked fine ever since. I'm still not sure why it
failed - the 12V regulator tends to run pretty warm/hot based on the
circuit, but I'm not sure if that had anything to do with it.

Hello all,
thanks to der Mouse, the pictures are available under:
ftp.rodents.montreal.qc.ca/pub/cheri/
If anybody could check out the DIP Switch settings ??
I could verify the status of the LEDs either, if this helps.
Just drop in an email.
There are two identical memory boards. The one scanned is the first, that's why the two terminators are missing .
The other memory board at the end of the bus has these terminators. Switch settings are different, apparently to set an ID.
Remember, I have no documentain, but it would be worth to compare the settings of the switches and LEDs
with a working unit !
Thanks in advance for any help !

I'm in need of 3-4 Psion Series 5 for the upcoming VCF. They're to be
used as portable terminals for the judges to use in scoring exhibits. I'm
trying to source them for under US$50 each. eBay has been OK and I've
gotten a couple from there already but most keep going for over $50 each
and my budget won't allow me to go higher.
Does anyone have any for sale, or know of where I can get some for under
US$50? I don't care if they are ugly or if certain non-critical parts are
broken (i.e. broken doors, latches, etc.) As long as it powers up, the
screen works, and the CF slot works then I'll be happy (of course I'll
want to pay less for such units).
Ideas?

Just roaming around the internet and ran across your thread----
Structured Design:
I have an SD 20/24 s/n 2197 ------ bought it new at my old company in 1986, I believe--
It has been in a locker for about 15 years----and yeah, no software that I could find, as of late
--my company is "gone", but I have the unit----
Works??? on powerup--busy light for a few milliseconds and then a green pass light-----
it hasnt been abused---or even used, in years---i.e."good shape"
24 pin ZIF socket, --you guys are talking about a 20 pin unit, I think?---
3 buttons ---verify, load , program
3 LED's busy, fail, pass
We did lots of GAL's on it---- 20V10 series, I have original GAL handbook, from Lattice also
we started doing hundreds of 16L8's and such from MMI, as well, back in 1986,7,8 and then went to the GAL's when they became "the thing"---
The hardware design changes were killing us in the early project phase--we burnt up 200 at a time with a particular minor hardware rev.
and I also have
*** 18 "magnetic wafers" --- for the drive, in the unit
and
*** "original" PALASM 4 (from AMD) on 5 floppys, version 1.1a-- I checked, and all read "a directory structure" ---2 thru 5 are all ZIP files
and a pile of PAL's,GALS, EPLD's which were from various sources---a lot of optical reprogrammable---samsung
some bigger than 24 pins, etc--I believe none are programmed, but I can't assure myself a few of the non-opticals are not used---
and, so they may not all apply to this programmer, obviously greater than 24 pins in some cases----
anyone interested?
Also---
Brand spanking new (old stock)----- still in the box, in the plastic bag:
Spectronics Spectroline PE-14T UV EPROM eraser
with the slideout tray for devices
"size of a carton of cigarettes"
Looks like it was never turned on---so I did
--timer 1 hour -----works,
UV lamp ------works,
Pull out drawer, UV turns off----works?
no holes in the black foam pad--couldnt have been used
and the original tech bulletin which tells you info on use of unit---energies of erasure, etc
we bought 2 in 1986 and sent the second one (this one) into the stock room, as a spare, and I found it in cleaning the shelves when we shut the doors-in 2001----
Also ,
B+C Microsystems 1409-PL.8 EPROM Programmer--open frameunit----- version 10 firmware ---------40 and 28 pin ZIF sockets
version 10.0 on 5 1/4 floppy for DOS and version 3.2 on 3 1/2 for mac drivers
Program light blinks 4 times on powerup--i.e. passes selftest----
And "The Book"--technical manual for the unit--build info--schematics
It also does all those 87xx smart controllers
and , of course, 2716--->27011
See BYTE magazine article MAY 1986, page 279 for info
and again, a pile of EPROMS with windows-----25,7----> 16, 32, 64, 256, 512, 1024
value--->???? I dont know--make me an offer?
Im a heavy duty Test Equipment designer guy, at this point----
excuse me for rambling-- any interest send me an email to:
wizardfz(a)earthlink.net
At 05:39 PM 10/12/2004, you wrote:

I have a friend looking for an IBM PC Server (see specific models below)
with a P/390 card and OS to play around with.
Has anyone got one for trade? He's not in a position to shell out cash
but he is in a position to trade you something tasty in return.
If you've got anything, please contact me directly and I'll put you in

Hi Tony,

I have determined that it is indeed the 1793 disk controller chip ...
I borrowed one from another system, and as soon as I powered up, I heard
the floppy seek to track 0 - stuffed in a boot disk and it booted right
up...
I agree :-( .. I don't have a spare 1793.
Does anyone have an extra Western Digital 1793 (or compatible) FDC
kicking around? Bare on on a board (I've got a good desoldering
station) ???
Regards,
Dave

Hi Dave,
You can still buy 1793s new from BGMicro for $4.49. Look on page 8 of
their catalog:

I have determined that the problem with my TRS-80 Model IV is a bad

Unfortunately I don't have a spare - does anyone here have an extra

I have no trouble sucking it off of a board if necessary.

Hi folks,
Had a mail from someone in the UK who's looking for said monitor since his
has died and the system it's connected to is still in use for archive stuff.
Writeups for the machine suggest that any monitor could be used but I asked
him to forward some pictures and it's not a standard monitor - the keyboard
plugs into it as well as there being 2x DB25 serial connectors for inputs
(and I guess outputs for the keyboard)..
If anyone's got a spare he's called John Charters and he's at
jcharters(a)inductotherm.co.uk. I can forward on the pictures he's sent if
it'll be of any help.
Ta!

Hi Marvin
If you get a machine running, I'll write some software, similar
to what I have on the H89 to transfer entire disk images. That
will make archiving easier.
I sent a message to Bob Bybee to see if he knew anything about
the other front panels. He was the editor for the Poly News.
Also, while digging through stuff, did you happen to come on
an extra serial interface card. I have a Poly88 that is sadly
without one.

Hello all,
thanks to der Mouse, the pictures are available under:
ftp.rodents.montreal.qc.ca/pub/cheri/
If anybody could check out the DIP Switch settings ??
I could verify the status of the LEDs either, if this helps.
Just drop in an email.
There are two identical memory boards. The one scanned is the first, that's why the two terminators are missing .
The other memory board at the end of the bus has these terminators. Switch settings are different, apparently to set an ID.
Remember, I have no documentain, but it would be worth to compare the settings of the switches and LEDs
with a working unit !
Thanks in advance for any help !
Pierre

Hey,
I have a copy of the setup program for the Vectra ES 12 computers. Do you
still need it?
Do you still have the HP 82321 Basic Language Processor cards and would you
like to sell them?

I'm looking for the book ASTOUNDING ARCADE GAMES FOR YOUR SPECTRUM+ &

published in the UK (13,000 copies).
Does anyone know where to locate one? I have a friend who's trying to
find it for some research he's doing.

It is amazing what can be found by looking around :). I had a box of
"stuff" from Polymorphic Systems that I finally got around to checking
out. I didn't realize that Polymorphic made a keyboard, but I have a
metal chassic with "Polymorphic" on it and about 6 keyboard assemblies
that fit inside. I also found a front panel to a System HD/18, a number
of "new" System 88/DS front panels, a System 8810 front panel, various
back panels, and enough wooden sides for another 5 computers or so. All
of the front panels have cutouts for full size 5 1/4" drives. Maybe this
will be the kick in the ... seat :) to get me going and backing up all
the Polymorphic disks (8" and 5 1/4" totaling probably a couple of
hundred disks) including source code and documentation for their
products.
Does anyone know what the HD/18 and 88/DS systems were all about? I've
got another box someplace that holds a pair of 8" drives with
Polymorphic logo on it, but I haven't had time to look through all the
engineering documentation to find out what it is.
I'm seeking out information on the Kid Newton, which was some special
version of Apple's Newton. Here's a photo:
http://www.msu.edu/~luckie/kidnewt.gif
This is for a client of mine but I'm not sure what if anything this
information will be worth. If you have a write-up or more photos of this
device (or you happen to have one) please contact me and we'll discuss
further.
Thanks!

Dave,
You are correct that BREAK at power up will bypass the attempt to boot
>from floppy, the Cass? / Memory? Prompts here are normal.
You are correct that without the floppy controller it will boot directly
to BASIC in ROM. Again Cass? And Memory are normal. Cass? is asking for the
cassette baud rate (L=500Baud or H=1500Baud). Memory? Reserves high memory
for use by drivers etc.
When the system at startup says 'Diskette?' it thinks it's sensing a disk
in the drive, for me this typically happens when the drive door is open with
a disk in the drive.
The best web site for info, docs and software is http://www.trs-80.com/,
you should find the service and disk owners manuals for download. Ira can
send you bootable floppies for the system; he's great to work with and knows
a lot about these old systems.
When I power up my Model III I hear the heads step back to track 0 thus
you are correct that this should happen.
I'm more familiar with the MODEL III however I believe the following
applies to the MODEL 4 as well:
When you removed the floppy drive for cleaning did you reconnect it to the
same position on the floppy cable? (Cable position defines the drive
number!) Assuming this is a standard RS floppy controller and cable then the
following is true: Radio Shack removed pins from the floppy drive connector
on the cable to control selecting the drive (typically either DS0/DS2 or
DS1/DS3 will be missing on the floppy controller side of the cable), they
jumper DS0-DS3 as all active on the disk drives (if you reset this then turn
them all back on). The internal floppy connector brings only DS0 and DS1
out. The external connector brings DS2 out as DS0 and DS3 out as DS1. Again
this is ONLY 100% true for RS controllers, some 3rd party controllers used
normal pinouts on the connectors so your mileage may vary.
The LAST drive on the floppy cable MUST be terminated (150 ohm typically)
otherwise the drives won't work.
Finally - if the drive is ALWAYS selected with the power on them you have
one of the cables on upside down, most likely the end to the controller PCB
as it's typically not keyed.
Hope something here helps. :)

Hi Guys,
Picked up another big load this weekend, and am just starting to go
through it - Item#1 is a TRS-80 Model IV.
When I first powered it up, it sucked on the Empty bottom drive for
a couple of seconds, then prompted with "Cass?" and entered ROM basic.
Tried a Model IV boot disk and go the same result - so I removed the
drive and cleaned it (machine has been sitting a long time).
Now, it powers up, selects the drive and "hangs" - does not move on
to the "Cass?" prompt - I've checked all connections and socketed
chips, and everything is clean and looks OK. Have reseated everthing
several times.
A few of observations:
- If I hold RESET while I power up the machine, the drive motors still
come on, but I do not get a select - the select appears to be happening
under software control.
- If I disconnect the disk controller board ribbon cable, the machine
powers up at the "Cass?" prompt - in this case, I believe the ROM
startup sees that there is no disk system and enters ROM basic,
thinking that it is a diskless unit.
- If I power-up/reset while holding BREAK, it also gives the "Cass?"
prompt - after briefly selecting the drive - looks like BREAK very
soon after power-up can interrupt the boot process, and ROM BASIC
comes up normally.
- I never see the drive seek - it selects, but does not seek.
If I manually move the drive head out during power-off, it DOES NOT
seek back to track-0 after selecting the drive when I power it on.
- Twice so far in a couple of hours of working on it, I have seen the
prompt "Diskette?" (no cursor) after powering on the machine (with
disk controller connected and not holding BREAK). I cannot make this
prompt come up reliably.
It looks to me as if something in it's interaction with the disk controller
is hanging the machine.
Anyone here knowlegable in TRS-80's?
Can anyone tell me what the Model IV is *SUPPOSED* to do on power-up, both
with and without a boot disk in the drive (I have no documentation at all).
Any pointers to service documentation? ROM listings? Other information on
servicing a model IV - any idea how I can further diagnose this problem?
Any help at all would be greatly appreciated!
Regards,
Dave

Scored this from the local "cleanup week", sans monitor, keyboard and mouse.
Has the DayStar Digital 100 MHz PPC upgrade board installed. Now, what do I
do with it? I have a keyboard and mouse on the way.
I have plenty of "standard" PC VGA monitors. Will these probably work? What
OS would suit this machine the "best". I am primarily a Xenix/Linux/Solaris
man, with a smattering of Microsoft products. Which OS will be the most
"usefull" I know the machine has at least 48 Meg of RAM. Not sure exactly
until I get it connected to a monitor.
What are the Pros and Cons of each OS?
Thanks for any suggestions,
Kelly
>* If indeed this is an S100 machine then don't do it!
Having never seen an S100 machine I can't say for sure, but I did open
the case today and there are no slots of any kind. Just a bunch of ICs
soldered to a single board (actually, two boards, but one appears to be
just for controlling the keypad and display).
My guess is, it is just a custom unit, and I really don't think it has
any value.
I have to dig thru my slide projectors, some of the info I found leads me
to believe some of the Kodak ones I have should support the remote
connector. I've never noticed a 7 pin connector before, but the way the
extra two pins are placed, I may have simply not paid attention when
plugging in a standard 5 pin remote. Baring finding a usable slide
projector, I'll be returning it to where I got it, curbside garbage.

Howdy,
I'm doing some archilogy in a local garage and finding some interesting
things. I've only just begun but I thought I'd ask if anyone would like
to see these scanned:
- tek 611 storage scope manual
- PDP-6 schematics
It looks like pdp-6 prints may already be in bitsavers - I'm not a pdp-6 person
Didn't see any 611 info.
